The cytologic findings in fine needle aspirates of two solitary pseudorheumatoid nodules are presented. The main characteristic of the smears was a necrotic granular and filamentous background accompanied by a granulomatous inflammatory infiltrate. The differential diagnosis is analyzed. The results in these cases indicate that the diagnosis of a solitary pseudorheumatoid nodule may be made by fine needle aspiration cytology after a critical evaluation of the cytologic and clinical data and with the help of special stains and microbial culture.

D012218	Rheumatoid Nodule	Subcutaneous nodules seen in 20-30% of rheumatoid arthritis patients. They may arise anywhere on the body, but are most frequently found over the bony prominences. The nodules are characterized histologically by dense areas of fibrinoid necrosis with basophilic streaks and granules, surrounded by a palisade of cells, mainly fibroblasts and histiocytes.
